In order to facilitate understanding of the core assembly lifting appliance provided in the embodiment of the present application, an application scenario thereof is first described below. The core assembly lifting appliance provided by the embodiment of the application is used for a static pressure molding line and applied to the field of casting production. Firstly, transporting mud cores on a three-dimensional warehouse line tray to a mud core pre-mounting seat of the static-pressure molding line by using a special lifting tool; then, the mud cores on the pre-mounting seat are clamped by a core setting clamp and then fall into the cavity. For some sand cores with smaller sizes, 2 groups of sand cores are placed on one preassembly seat, the lifting points are positioned in the east-west direction, and a space is reserved in the east-west direction, so that 2 persons can work. But the hoisting device is inconvenient to use in large core assembly hoisting, because the hoisting point of the large core assembly is in the north-south direction, the south is the equipment, and 2 the personal operation is very inconvenient. Therefore, the embodiment of the application provides a core assembling lifting appliance to solve the problems. The following detailed description is given with reference to the accompanying drawings and examples.
Referring first to fig. 2 and 3, fig. 2 shows a schematic structural diagram of a core assembly spreader provided by an embodiment of the present application. Fig. 3 shows a schematic structural diagram of another angle of the core assembly spreader provided by the embodiment of the present application.
The core assembling lifting appliance main body structure provided by the embodiment of the application comprises three parts, namely a support frame 18, a clamping device and a linkage locking mechanism. The support frame 18 serves as a support structure for supporting the clamping device and the interlocking mechanism. The clamping device is used as a main functional structure for clamping the core assembly and is used for clamping and fixing the core assembly. The linkage locking mechanism is used as a driving mechanism and used for driving the clamping device to clamp the core assembly and lock the clamping device, so that the clamping device can keep the state of clamping the core assembly. The structure of the core assembly sling is described in three parts.
With continued reference to fig. 1, the support frame 18 is a frame structure that is a cross frame, i.e., a frame formed by splicing cross beams and vertical beams, to form a body member that supports the core assembly and other structures in the apparatus.
The support frame 18 is welded by square steel pipes, so that the weight is reduced, and the structural rigidity can be ensured.
When cooperating with the clamping device, the clamping device comprises two clamping frames, a first clamping frame 2 and a second clamping frame 10, respectively. The first clamping frame 2 and the second clamping frame 10 are respectively arranged at two ends of the supporting frame 18, and the first clamping frame 2 and the second clamping frame 10 are respectively hinged with the supporting frame 18. Taking the first clamping frame 2 as an example, one end of the first clamping frame 2 is hinged with the supporting frame 18, and the other end is used for core assembly.
The support frame 18 further comprises a triangular frame assembly disposed on the transverse frame as a connecting structure for cooperating with a spreader. Illustratively, the supporting frame 18 is provided with a lifting ring 7, and the lifting ring 7 is used for connecting with hoisting equipment for hoisting and carrying the whole core assembly sling. When the hanging ring 7 is specifically arranged, the hanging ring 7 is assembled on the triangular frame group.
When the triangular frame group is specifically arranged, the triangular frame group comprises two triangular frames, the two triangular frames are arranged along the width direction of the transverse frame, and the two triangular frames are fixedly connected through the cross beam, so that the triangular frame group is integrally formed. The lifting ring 7 is fixed on the cross beam. In the specific assembly, the suspension ring 7 may be fixed to the cross beam by a threaded connector (bolt or screw), or may be fixed to the cross beam by welding, which is not specifically limited in the embodiment of the present application.
With continued reference to fig. 1, the support bracket 18 is also provided with a stop 19 for abutment with the core assembly. The stop 19 is arranged on the downwardly facing surface of the transverse frame. When specifically setting up, the number of stopper 19 is four, and four stopper 19 set up the corner position at horizontal frame respectively.
When the limiting block 19 is specifically arranged, different modes can be adopted for arrangement, for example, the limiting block 19 and the support frame 18 are of an integral structure, or the limiting block 19 is fixed on the support frame 18 in a welding or bonding mode, and in the embodiment of the application, specific limitation is not made.
When the limiting block 19 is fixed specifically, the limiting block 19 is fixed on two vertical beams of the support frame 18. Of course, the device can be arranged at other positions according to requirements.
In addition, it should be understood that the four limiting blocks 19 are specifically arranged between the two clamping frames to ensure that the limiting blocks 19 can be in abutting contact with the core assembly when the clamping frames clamp the core assembly, and cooperate with the clamping frames to fix the core assembly.
With continued reference to fig. 2 and 3, the first 2 and second 10 clamping frames of the clamping device are arranged at both ends of the supporting frame 18 and are respectively hinged with the supporting frame 18. Taking the first clamping frame 2 as an example, one end of the first clamping frame 2 is hinged with the supporting frame 18, and the other end is used for core assembly.
The first clamping frame 2 and the second clamping frame 10 are oppositely arranged at two ends of the supporting frame 18, and when the first clamping frame 2 and the second clamping frame 10 rotate relative to the supporting frame 18, the clamping device can be opened and closed. When clamping the core assembly, the clamping device is first opened, i.e. the first clamping frame 2 and the second clamping frame 10 are respectively rotated in a direction away from the supporting frame 18, and the opening between the first clamping frame 2 and the second clamping frame 10 is enlarged. When the core assembly is clamped, the first clamping frame 2 and the second clamping frame 10 rotate towards the direction close to the supporting frame 18, the opening of the clamping device is reduced, and the core assembly is clamped and fixed.
The first clamping frame 2 and the second clamping frame 10 can be welded by square steel pipes, so that the weight is reduced, and the structural rigidity can be ensured.
When the first clamping frame 2 and the second clamping frame 10 clamp the core assembly, the core assembly is clamped and fixed by the core hanging positioning plate. Namely, each clamping frame is provided with a core hanging positioning plate matched with the core assembly.
As shown in fig. 2, a first suspension core positioning plate 1 is provided on the first clamping frame 2, and a second suspension core positioning plate 11 is provided on the second clamping frame 10. The first hoisting core positioning plate 1 is positioned at one end of the first clamping frame 2 far away from the supporting frame 18; the second suspension core positioning plate 11 is located at one end of the second clamping frame 10 far away from the supporting frame 18.
Illustratively, the first core positioning plate 1 protrudes outward from the side of the first clamping frame 2 facing the supporting frame 18, and the second core positioning plate 11 protrudes outward from the side of the second clamping frame 10 facing the supporting frame 18, so that the two core positioning plates can clamp and fix the core assembly when the first clamping frame 2 and the second clamping frame 10 are closed.
The first core positioning plate 1 and the second core positioning plate 11 are both in a strip-shaped structure, and the length direction of the first core positioning plate and the second core positioning plate is along the width direction of the core assembly, so that the contact area between the first core positioning plate and the core assembly can be increased, and the clamping effect is further enhanced.
As an optional scheme, when the hoisting core positioning plate is arranged, the shape of the hoisting core positioning plate is matched with the groove at the position of the hoisting point on the core assembly. That is, the shape of the first hoisting core positioning plate 1 is matched with the groove at the hoisting point position on the core assembly; the shape of the second core positioning plate 11 is matched with the groove at the position of a lifting point on the core assembly. So that the first core positioning plate 1 and the second core positioning plate 11 can be respectively matched with the groove of the lifting point position on the core assembly when the core assembly is clamped.
With continued reference to fig. 2 and 3, when the first clamping frame 2 and the second clamping frame 10 are specifically provided, the first clamping frame 2 and the second clamping frame 10 are respectively provided with a connecting structure protruding above the supporting frame 18, and the connecting structure is used for being in fit connection with the linkage locking mechanism. When the linkage locking mechanism drives the first clamping frame 2 and the second clamping frame 10 to open, the linkage locking mechanism can drive the two connecting structures, so that the first clamping frame 2 and the second clamping frame 10 synchronously rotate relative to the supporting frame 18, and the rotation directions of the first clamping frame 2 and the second clamping frame 10 are opposite.
With continued reference to fig. 2 and 3, the interlocking locking mechanism is used to drive the two clamping frames to open and close synchronously relative to the supporting frame 18 and can be locked at a set position. The linkage locking mechanism has two functions, one is to drive the two clamping frames to rotate synchronously, and the other is to lock the two clamping frames when the two clamping frames rotate to a set position, so that the two clamping frames are kept at the position. Wherein, the setting position is the position of clamping and fixing the core assembly by the two clamping frames.
The linkage locking mechanism that this application embodiment provided mainly wraps up carousel 5 and connecting rod, and wherein, carousel 5 rotates with support frame 18 to be connected and can lock in foretell settlement position, and the connecting rod is as the connecting piece for it is articulated respectively with the clamping frame to connect carousel 5. Wherein, one end of the connecting rod is hinged with the clamping frame, and the end of the connecting rod far away from the clamping frame is hinged with the turntable 5. Illustratively, when the number of the clamping frames is two, the number of the corresponding connecting rods is two, and the two connecting rods are respectively arranged on two sides of the rotating disc 5 to facilitate connection.
The two links are named a first link 4 and a second link 8, respectively, for convenience of description. One end of the first connecting rod 4 is hinged with the rotary table 5, and the other end of the first connecting rod is hinged with the first clamping frame 2, and is particularly hinged with a connecting structure of the first clamping frame 2; one end of the second connecting rod 8 is hinged with the rotary table 5, the other end is hinged with the second clamping frame 10, and the second connecting rod is particularly hinged with a connecting structure of the second clamping frame 10
More specifically, when the connecting rods are hinged with the clamping frame, the linkage locking mechanism further comprises a connecting head corresponding to each connecting rod; wherein, one end of the connector is hinged with the corresponding connecting rod; the other end of the connector is hinged with a clamping frame corresponding to the connecting rod. Illustratively, the number of the connectors is two, namely a first connector 3 and a second connector 9; one end of the first connecting joint 3 is hinged with the first clamping frame 2, and the other end of the first connecting joint is hinged with the first connecting rod 4; one end of the second connector 9 is hinged with the second clamping frame 10, and the other end is hinged with the second connecting rod 8;
from the above description, when the turntable 5 rotates, the first connecting rod 4 and the second connecting rod 8 are respectively driven, the first connecting rod 4 and the second connecting rod 8 respectively drive the first connecting head 3 and the second connecting head 9, and the first connecting head 3 and the second connecting head 9 respectively pull the first clamping frame 2 and the second clamping frame 10, so that the force transmission is realized, and the first clamping frame 2 and the second clamping frame 10 are controlled to open and close.
With continued reference to fig. 2 and 3, the turntable 5, when rotatably coupled to the support frame 18, is rotatably coupled to a cross member of the support frame 18. Specifically, the supporting frame 18 is rotatably connected with a rotating shaft 17, and the rotating disc 5 is fixedly connected with the rotating shaft 17. The rotating shaft 17 is arranged on a cross beam of the supporting frame 18 in a penetrating way and can rotate relative to the cross beam, and the rotating disc 5 is fixedly connected with the rotating shaft 17. So as to be rotatable about the rotary shaft 17 when the rotary disk 5 is rotated.
In addition, in order to facilitate the rotation of the rotating disc 5, the rotating disc 5 is further provided with a rocking handle 13 for driving the rotating disc 5 to rotate relative to the supporting frame 18. As shown in fig. 2, the number of the rocking handles 13 is two, and the two rocking handles 13 are arranged on two opposite sides of the rotating disk 5. When the rotary disc 5 is rotated, force can be applied through the rocking handle 13 to drive the rotary disc 5 to rotate.
Illustratively, the handle 13 is an inverted L-shaped handle to facilitate application of force. The rocking handle 13 can be connected with the rotary table 5 in different ways such as a threaded connection or a welded connection.
In order to limit the rotating angle of the turntable 5, the linkage locking mechanism further comprises a limiting column 12 arranged on the turntable 5; when the rotary disc 5 is locked to the set position, the limiting column 12 is pressed against the supporting frame 18.
